‘SpaDeX Mission Crucial For India's Ambitious Space Station’: ISRO Chief S Somanath

Sriharikota: After the launch of the PSLV-C60 rocket on the SpaDeX mission, the Indian Space Research Organisation ( ISRO ) Chairman Dr S Somanath announced that the launch of the PSLV-C60 rocket, carrying the SpaDeX mission and 24 payloads was successful. The rocket lifted from Sriharikota at 10 pm on Monday. The ISRO chief expressed confidence in the success of India’s space docking mission, following the successful placement of two spacecraft into orbit.

The PSLV-C60 rocket, launched late Monday night, marks a major milestone for ISRO as it works towards mastering space docking technology, a crucial step for future missions like Chandrayaan-4 and India’s planned space station by 2035.

Rocket Place The Satellites In Right Orbit: S Somanath

ISRO Chairman Dr S Somanath said, "I announce the successful launch of the PSLV-C60 for the SpaDeX mission. The rocket has placed the satellites in the right orbit.”

“Congratulations to the entire team of the PSLV project who put the satellites in the right orbit. Also, the SpaDeX team worked in a very innovative, novel, cost-effective docking demonstration mission using two small satellite bus architectures," Somanath congratulated his team for the successful mission launch.

Speaking at the Mission Control Centre, Somanath explained that the two spacecraft, Spacecraft A and B, were successfully placed in a circular orbit 475 km above Earth. He also mentioned that the docking process would begin in the coming days, with expectations for it to take place around January 7.

“The rocket has placed the spacecraft in the right orbit, and the two SpaDeX satellites will now move one behind the other. Over time, they will travel about 20 km apart before beginning the rendezvous and docking process,” said Somanath. He highlighted that this mission is crucial for ISRO's future goals, including its human spaceflight program and space station development.

India Fourth Country To Possess Space Docking Technology

The SpaDeX mission is a cost-effective technology demonstrator that aims to develop and demonstrate the technology needed for the rendezvous, docking, and undocking of two small spacecraft in a low-Earth circular orbit. This mission brings India closer to becoming the fourth country in the world to possess space docking technology.

The mission, referred to as SpaDeX, is a historic step in demonstrating space docking capabilities, which are vital for missions involving satellite servicing, interplanetary exploration, and the construction of space stations. Somanath stated that India is now on track to join an elite group of countries that have achieved space docking, including China, Russia, and the United States.

Remarkable Step In Expansion Of Space Activities: ISRO Chief

Somanath also noted the importance of the POEM-4 payload, which includes 24 research payloads from various industries, academia, and ISRO centres. These payloads will conduct important experiments, including biological studies and debris capture, during the mission.

“This is a very important mission for us, especially with the expansion of space activities and reforms in the space sector,” Somanath added. “We hope to achieve the docking process soon and continue to build on this technology for future space missions.”

ISRO’s progress with SpaDeX is not only a step toward advancing space exploration but also a significant achievement for India as it aims to strengthen its position in the global space community.

The 24 payloads onboard the PSLV-C60 include a range of scientific experiments and technology demonstrations. Some of the notable payloads include:

- POEM-4 Payloads: 14 payloads from ISRO/DOS centres and 10 payloads from non-government entities, including academia and start-ups.

- R&D Payloads: Experiments such as the Walking Robotic Arm, Debris Capture Robotic Manipulator, and Gradient Control Reaction Wheel Assembly.
